Solar activity has further reduced. Only two C1 flares and a few almost C flares erupted. NOAA active regions 2248 and 2249 have potential to produce a few more flares at the C-level. M-class flares are also possible, but not very likely (20%). No Earth-bound CMEs were observed. The solar wind has slowed down to about 380 km/s. The interplanetary magnetic field reached a magnitude between 5 and 10 nT, with a fluctuating Bz component. Geomagnetic conditions are quiet and are expected to remain so, with some chance for a few time slots of unsettled to active levels.
